Attention with Prior
A prior is an attention distribution that comes from a source other than the immediate pairwise input interactions (such as the standard in a vanilla Transformer). Attention with prior is the fusion of two attention distributions, which can be done by computing a weighted sum of the scores corresponding to the prior and the generated attention before applying the softmax function.

Linear Attention
A research team is working to reduce the computational cost of the attention mechanism for processing extremely long documents. Their proposed solution involves modifying the attention calculation so that each query token only computes attention scores with a small, fixed subset of key tokens (e.g., neighboring tokens and a few globally important tokens) instead of all tokens in the sequence. Which category of attention improvement best describes this approach?
